IMPROVEMENT iN LAMPS.

Specification forming part of Letters Patent No. 36,649, dated October14, 136:2.

To all whom, it may concern:

Be' it known that I, PETER HAYDEE', of the city of Pittsburg, Alleghenycounty, and State of Pennsylvania, have invented a new and usefulImprovement in Lamps; and I do hereby declare that the {ellen-'ing is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, making apart of this specification.v

In the diii'erent figures like parts of the burner are represented bythe same letters.

Figure l represents a vertical central section ofthe burner, and showsthe mode ofoperating the slidingwick-tube. Fig. Zrepresents a horizontalprojection of the burner with the upper and inner caps removed, andshows the chimney-ring and clasp and the position of the wick-tube, andthe wheels for operating the wickftube and wick at the base of theburner. Fig.,3 represents the mode of attaching the auxiliary wick andthe operation ofthe principal wick. Fig. Ll. represents a perspective ofthe burner placed upon a'lamp, and shows the shape'of the upper cap.

a a represents the base or basketlike pai-t of the burner, which isperforated for the admission of air, and includes th-e chimney-ring,whe'rrthat is used..

b I) represents a cone or cap attached to the base by means ofVspriiig-catches, as shown at p p p, and is divided at the top into fourparts. Two opposite parts are b ent outward and form projections, asshown at c c.. rIhe other two opposite parts are about the width of thewicktube at the base, and somewhat semieireular at the top, convex onthe outside, and inclined toward each other, formingthc mouth of theburner, as shown at d.

cie shows the projections of the cap b.

d shows the mouth of the cap c e represents the inner cap or conc, whichcovers the pinion-wheels. The upper part extends nearly to the base ofthe mouth of-the cap b. Thewick-tube passes through it, leaving a smallerevi ce at each side for the passage of vapor and gases from the bodyof the lamp vdirectly into the ilame, thus preventing the escape ofunconsumed gases. This cap is eireular at its base and a attened coneiitting the wick-tube at its edge at the top.

f represents thewiek-tube. It is perforated on one side, -so that theeogs of the pinionwheel Work into it lfor raising or lowering thewick-tube. On the other side there are two strips cut out of it to giveplay to the wheels running the wick. The strip remaining between thewheels is bent inward at the bottom for the suspension of an auxiliarywick, which may be common candle-wick or fluid-wick, as represented at'Zm' Z. v

g represents the pinion for operating the wicletlibe.

h represents the pinion i'or operating the f1? I represent a wire claspfor holding the chimney. It ishinged in the middle, and bent as shown atv, and it extends only about twothirds around the chimney-ring, andclasps on its edges, as shown at n n. It can be thrown hack, as in Fig.4, and clasped on after the chimney is inserted.

7.'. represents the principal wick.

7 I represent the auxiliary wick.

m represents the hook fort-he suspension of the auxiliary wick.

o o e represent three ridges for the chimney to rest upon. v

a a represent the clasps of the chimneyholder.

p p p represent the spring-catehcs for holding the cap Z.

q represents the collar of the burner, which is -i'astened to the lamp.

r i' represent the lamp in perspective. y

s s represent an open space in the base-of the burner, to formaconnection between the lower chamber of the burner and the font of oil,and thus preventing the accumulation of heat in this part of the burner,and condensing bythe cooling influence of the font below any vapors thatmay arise.

Having now described the burner, I will proceed to describe itsoperation.

This burner is designed to burn carbon or coal oil either with orwithoutthe use-of a glass chimney; but it will also burn camphine,burning-fluid, whale-oil, and the other illuminating-oils. The fontheilig supplied with oil and the burner being supplied with wick, tolight the lamp raise the wick by the pinion l1. and light it. It can beignited at any part of the mouth of the burner. The quantity of lightand also the amount of draft are regulated bythe movements of thewick-tube and Wick, both of which can be run up the mouth of the burner.The draft is increased by lowering the sliding tube inthe mouth of theburner, and vice versa, and. the quantity of light for each position ofthe sliding tube depends on the elevation of the wick above the.

tube. rIhus a perfect control is had over the draft and light, and theburner will burn with or Without a chimney. The projections c c serve tospread the dame, and by supplying the edges of the ilame with a currentof hot air from the cap b prevent their smoking. As a small portion ofthe flame rests within the mouth of the burner the light is veryportable and is not easily blown out by the wind, so much so that it canbe carried in the open air even withastrong draft of wind. The cap b, orany ordinary cap, can be used when a chimney is put on. Y. A muchshorter chimney can be used with the cap b, and a more mellow lightobtained than with the ordinary chimney-lamps. Thechimney is designed torest on three or more ridges in the chimney-ring, to prevent it fromgetting too hot. The cap b may rest on ridges in the same way, toprevent the base of the burner from getting overheated. The auxiliarywick is designed to keep up a regular supply of oil on the princlpalwick, and when the oil is Yyerylight and the font shallow the auxiliarywick can be left out; but in coal and carbon oil much diiculty has beenexperienced when the oil is heavy and the font deep, and this auxiliaryWick, lying in contact with the principal wick at the point m,isdesigned to remedy this difficulty. Y

In small lamps, designed Vto be used entirely Without a chimney, thechimney-ring can be omitted. The shape of thebase a a is not ma terial,so that it is suflicientl y perforated. The pinion g may be reversed,with the handle on the opposite side from the pinion h. Instead of thewhole tube f sliding, it may have a slide at its top answering the samepurpose.

In the above specicationI claim and desire to secure by Letters Patentof the United States- A wire clasp extending about two-thirds around thechimney-ring, shaped and operating as described.

PETER HAYDEE.
